environment, if only a long connection (after the system parameter tuning), the data will often depend on the drop rate. In the case of a stable connection, the heartbeat time is not affected, and the internal QPS achieves a 300W long connection in an acceptable state of pressure measurement. The online single machine is actually used up to 160W long connection, divided into two instances. The on-line scene of the QPS is related to egress bandwidth,
